Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603088, here are decompositions:

61 + 31603027 = 31603088
79 + 31603009 = 31603088
157 + 31602931 = 31603088
211 + 31602877 = 31603088
229 + 31602859 = 31603088
397 + 31602691 = 31603088
409 + 31602679 = 31603088
457 + 31602631 = 31603088

Showing the first eight; more decompositions exist.
